Hello,
That's my first post here so please don't be irritated by a newbie question. I would also like to apologise for my English as it is not my native language.
I have decided to transfer my old VHS tapes to a PC. Many of them are, unfortunately, of very poor quality. Thus I tried to improve them with the help of AviSynth. But I think that the script I came up with did more harm than good. Here it is:
AVISource("input1.avi")
SmoothDeinterlace()
#LeakKernelDeint(1)
ConvertToYUY2()
Cnr2("xxx",4,5,255)
GuavaComb(Mode="PAL", Recall=75, MaxVariation=25, Activation=40)
PixieDust(5)
Crop(8, 0, -12, -16)
ConvertToYV12()
ColorYUV(cont_v=-24, opt="coring")
Levels(0, 0.96, 255, 0, 255)
BicubicResize(640, 480)
I tried to follow the guide on TV capturing but couldn't find a way to properly deinterlace video. I've tried KernelDeint, LeakKernelDeint, LeakKernelBob, Telecide, SmoothDeinterlace but all of them doesn't seem to do a good job. The best, I think is to use the same method as in VirtualDub, to blend field together, but I don't know which filter for AviSynth do I need to use.
The second problem is that strange artifacts appear when I am viewing the clip frame-by-frame in VirtualDub or VirtualDubMod. They remain when I compress the video so some frames look terribly. And what is puzzling, the same frame renders differently when you return to the beginning of the clip and then go to this frame again. Here you can see more. (http://smc2k.ifastnet.com/avis.html)
Thanks for your help in advance.
